[Answer] 1. Where was the world's first revolving door installed?

Step 1 : Introduction to the question "1. Where was the world's first revolving door installed?"

...1. At a hospital in Calcutta, India 2. At a kangaroo farm in Sydney, Australia 3. At a school in Juneau, Alaska 4. At a restaurant in Times Square, New York The first patent for a revolving door was granted to a German designer, H. Bockhacker, in 1881. It was Theophilus van Kannel of Philadelphia, however, whose patent was granted in the United States in 1888, that would introduce the production of these dizzying doors. This came about in due course in 1899 with the installation of the world's first revolving door at Rector's restaurant in Times Square. The disadvantages of a poorly designed revolving door can see one trapped in same like an unfortunate goldfish, but the advantages of an efficiently working spinning door outweigh this. They're energy efficient and prevent the onslaught of cold wintry drafts, which in turn lowers the costs of interior heating. They allow many people to pass in and out of large buildings without tripping over each other, they can be designed for security purposes to allow only one person at a time into restricted areas, they block out external noise, they can't be blown open in strong winds, and they're quite visually appealing. They are, however, a minefield for mothers with prams, and those people who use a wheelchair for mobility purposes, so in these cases, a side door that opens normally is usually installed as well. Comically so, in most countries that have right hand side of the road drivers, revolving doors open counter-clockwise. In countries, such as Australia and New Zealand, with left hand side of the road drivers, the doors open in a clockwise fashion. Britain, however, just to make things even more confusing, has revolving doors that can go in either direction, so in that country you won't know if you're coming or going.
